Which of the following actions would constitute a breach of duty by a real estate agent?

A real estate agent has a fiduciary duty to act in the best interests of their client, which includes loyalty, full disclosure, and putting the client's needs ahead of their own. Acting in self-interest over the client's best interest directly undermines this duty. This could manifest in various ways, such as prioritizing personal financial gain or making decisions that benefit the agent instead of the client. This behavior not only violates the trust placed in the agent but also may lead to legal repercussions for breaching fiduciary responsibilities.

In contrast, providing thorough and accurate property information, negotiating fair terms for both parties, and adhering to ethical guidelines and laws are all actions that support the agent’s duty to their client and the integrity of the real estate profession. These actions are essential for maintaining professionalism and trust and do not constitute a breach of duty.
